So this is a netbook, there is no cd/dvd drive, hence using the usb stick. Would this shortcut to the command prompt work when booting from that? and when you say first screen, would that be the first non-bios screen i get to?

Yes it will work for sure. You can press it from the screen of choosing the language and keyboard layout.
